Symptom

Remarks

1.

The TV takes several seconds to respond to

• It is normal for digital channels to take longer to tune in.

 

channel changes.

• Press ENTER after entering a channel number to minimize

 

 

delays.

 

 

• Use a 4-digit number for an over-the-air digital channel.

 

 

• Use a 6-digit number for digital cable channels if your cable

 

 

service is able to recognize 6-digit channel numbers.

 

 

 

2.

You cannot access a channel.

• Use number keys instead of CH.

 

 

• Be sure the channel you want to view is in memory.

 

 

• Check that the TV is switched to the correct device or

 

 

antenna for that channel by pressing the INPUT key.

 

 

• Make sure the Lock > Parental menu lock is set to Off.

 

 

• If you cannot tune to a virtual digital channel even though

 

 

the TV has already memorized digital channels, tune to the

 

 

physical channel number used by the broadcaster. The

 

 

virtual channel will then be automatically added to memory.

 

 

• You may be trying to tune to an analog channel that is no

 

 

longer broadcasting.
